Well, I got inspired and started digging through the SUSE Kickoff branch and found some useful additions for the Kcontrol module.
I figured I'd try and integrate them into my Gentoo Kcontrol ebuild and found that it was no trouble at all.
First off, it now has the ability to select between the Legacy K-Menu and the new Kickoff (SUSE) menu via a dropdown.
Then, further down, I added a section to allow modifying some of the other hidden options. I still have a couple of more to add to the Kickoff Menu section, but that will happen later.
The module also now intelligently disables/enables certain areas depending on what features are actually available for the currently selected menu.
